Double Glazing Questions and Answers for Harrow residents:


Can I get free double glazing?

If you are over the age of 60, living on benefits, or otherwise in dire need of assistance, you may be able to get free double glazing. You will need to check with the benefits office.


Is it worth replacing old double glazing?

Yes, if they are misting up or condensation is appearing between the panes. Remember, some double glazed windows are better than others, and triple glazed windows can be better still. Check warranties and guarantees. Replacing old double glazed windows with new higher performance glazing will cut heat loss through your windows, making the room more comfortable and easier to heat. It can also cut your heating bills slightly.


What are the benefits of double glazing?

Less condensation – Double glazed windows reduce the amount of moisture on the inside of your windowpanes, as the airtight seal prevents the condensation from building up. Single glazed windows often allow condensation to build up which causes windowpanes to produce mold. Also there will be less external noise.


What does double glazing mean?

The actual definition is: two layers of glass with a small insulating gap in between set in a window to reduce heat flow in either direction.


Will double glazing make my house warmer?

Yes, Single glazing is not considered a suitable option for the majority of modern homes. It won’t effectively trap heat, whereas double glazing will keep your home comfortable for longer


How many years does double glazing last?

The general consensus from manufacturers on the lifespan of double glazing is estimated to be anything between 20 and 35 years depending on the manufacturer and the fitter. Some people even suggest up to 40 years if looked after.


Are the window sills replaced with new windows?

No, even though windowsills receive the majority of moisture from open windows, they are never replaced during the window replacement process. That is a job for a good joiner.


Does double glazing keep a house cool?

Yes, Double glazing is very effective in all weathers because it stops heat transferring from one side to the other. That means in winter, it stops heat escaping from the inside of the property and in hot weather it limits the amount of heat energy from the sun transferring to inside the building.


Does double glazing really make a difference?

Yes, double glazing can be as effective as improving your home’s insulation and reducing external noise by up to 70%.


How much energy do you save with double glazing?

As mentioned previously, double glazing can improve insulation by up to 70% which means its costs less to heat your home. In 2022 we have seen huge energy cost increases, so it is vital for most people to reduce heating bills.


How do you know if your double glazing needs replacing?

The clear signs that you need to replace your windows are:

  1. There Are Draughts Around Your Windows
  2. There Are Chips or Cracks in the Windowpane
  3. You have Condensation on the glass
  4. Your Windows Have Water Leaking In
  5. Your Energy Bills Have Been Increasing
  6. Difficulty Using Windows


Which is better aluminum or uPVC windows?

As Aluminium is stronger than uPVC, this means aluminium windows have thinner frames, which some people prefer. In most cases it is an aesthetic decision rather than a performance decision.


Does double glazing reduce noise?


Yes, it definitely does. Double glazing by it’s nature is a noise reducing system of insulation or soundproofing. As it comprises of two panes of glass, with an air gap in the middle, and a specialised frame.


How long does it take to install double glazing windows?

On average, each window takes anything from 1 hour to 3 hours for a fitter to install. The actual time it takes to install the window will be different depending on the size and type of window.
